Definitions

  • the present invention relates to toy railways and in particular to a toy cog railway.
  • Cog railways are used on steep slopes where static friction alone may not be sufficient to overcome gravity.
  • Toy cog railways have heretofore been constructed as small scale versions of actual cog railways. Accordingly, the track for the railway has been provided with a center rack between two rails.
  • the associated train includes a cog wheel that is driven by an electromotor of the train engine to engage the rack.
  • Actual cog railways may employ one of several systems (e.g. Riggenbach, Abt, Strub, and Locher) although toy cog railways usually employ the Strub system which utilizes upper open cogs since this simplifies the manufacture of the rack as well as the engine.
  • Model cog railways heretofore available also suffer from a shortcoming of actual cog railways in that the maximum steepness of the track slope is relatively small particularly on tight turns.
  • the engine be prevented from "lifting" off the rack.
  • model cog railway's can only be used to a very limited extent for "pushing” since the pushed cars tend to leave the track particularly on steep slopes and tight turns.
  • a toy comprising a vehicle in the form of an imaginary animal figure designed to travel on a horizontal, substantially smooth track mounted on a support.
  • the track is in the form of an approximate oval formed of two parallel side sections and curved end sections.
  • the track has a vertical cogging rack throughout its entire length on its inner edge which is engaged by a battery driven cogwheel.
  • the vehicle moves in one direction along the straight sections of track and reverses direction in the curved end section.
  • the vehicle is guided along the track by a shoe that rides in a recess of the track between the rack and outer track edge.
  • a toy that operates with a somewhat similar movement is also disclosed in French patent 517,106.
  • This toy is also provided with a closed approximately oval track with a vertically extending rack on the track inner face.
  • a vehicle that moves along the track is provided with a drive motor and a drive cog that engages the rack and which is so constructed that that as it moves it also rotates two airplane models mounted on two cantilevers.
  • a further object is to provide such an model cog railway wherein the track may readily and easily be laid out in any desired shape without any particular skill or expertise.
  • a model cog railway comprising a model track and model engine.
  • the track comprises a smooth driving face on which a cog member extends longitudinally.
  • the cog member is provided with two transversely separated racks of vertically extending cogs symmetrically disposed with respect to the drive face.
  • the engine is provided with a pair of guides positioned opposite each other to engage one each of the track racks.
  • the engine is further provided with a drive motor having a single drive cog wheel which is offset with respect to the center of the separation between the guides so as to engage one or the other of said track racks
  • Coupling devices are also be provided between the engine and nondriven cars to prevent such cars from derailing on steep slopes or curves. These devices serve to apply the moving force for the cars as close as possible to the driving face of the track and center of gravity of the car.

On the other hand if all of the tongues were shaped as tongue 71 the train cars would run unsteady at any speed. Thus it is advantageous to use both style tongues 70, 71 which can both be received in slot 68 of the coupling yoke 23.
